To all whom it may concern 1 Be it known that I, ALBERT F. CARTON, a citizen of the United States, residing at Pipestone, in the county of Pipestone and State of Minnesota, have invented certain 7 new and useful Improvementsin Seed-Corn Driers, of which the following is a specifica tion.

1 This invention is a seed corn drier and has for its efficient: structure for supporting ears of seed 'corn therein for permittin of free circulation of heat abont the ears or positively drying the corn.

Another object of this invention is the production of a seed corn drier which is provided with a plurality of removable racks, means being carried upon the racks for supporting the ears of seed corn, whereby the racks may be easily inserted into the casing after being filled with corn to be dried or may be readily removed from the casing after the corn has been dried.

Another object of this invention is the production of a seed corn drier whereinthe racks. are provided withelongated ribs,

while clips are provided for gripping the ribs and releasably carrying ears of 7 seed corn thereon, thus causing the earsto be maintained in vertical and substantially I parallel arrangement, thus allowingthe heat to .freely circulate between the ears for drying the corn.

Another object of this invention is the production of a seed corn drier, wherein a heating drum is carried within the caslng and is supplied with heat from a lamp positioned therebelow, thus allowing the heat to pass from the drumand freely circulate through the racks for drying the corn supported thereon. a i One practical formof construction and assembly of the present invention will be hereinafter described and is illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the seed corn drier, portions of the heating drum and lampbeing broken away. i Fig. 2 's a top plan view-of one of the racks. Fig. 3 is an enlarged side elevation of one of the clips, showing a rib of one rack in Specification of Letters Patent.

principal object the production of an f SEED-CORN DRIER.

Application filed June 3, 1918. Serial No. 237,961.

In the preferred embodiment of the present invention, about to be described, it will be seen that the base 5 of the casing is provided with suitable supporting standards 6. The inclosed casing 7 is carried upon the base 5 and has doors 8 hinged thereon in any suitable manner. It is therefore seen that the doors may be swung to a closed po sition for closing the casing, although when so desired the doors may be swung to an open position, as illustrated in Fig. 1. The ventilator 9 is carried by the top of the casing 7, as clearly shown in Fig. l and thus provides means for allowing the surplus heat to escape as well as the moisture which will arise when the ears of corn are being dried. p

Thelamp casing 10 is positioned in the casing 7 and rests upon the base 5 and carries a lamp 11 therein. This lamp 11 may be of any suitable construction for heating the heating drum to be. hereinafter described and it is of course obvious that any other suitable form of heating means may be employed for heating the interior of the casing 7, without dep of the present invention.

A plurality of horizontally extending supporting cleats 12 are carried within the casing 7' and in horizontal alinement with each-other on opposite sides of the casing as also shown in Fig. '1. These cleats are spaced apart for supporting the heating drum and the racks to be hereinafter described. i V

The heating drum consists of a platform 13, l which is substantially rectangular as shown in Fig.4 to conform to the shape of the casing 7. It is of course obvious that the casing may beof any desired shape to conform to the contour of the interior of the casing. ;.The hollow drum 14 is carried or formed upon the platform 13 and it will be noted that the platform 13 is provided with an opening 15. forpermitting the heat of the lamp to pass through theplatform and into the inter or of the drum 14. The necks 16 lead from the top of the drum 14: in spaced relation with respect to each other, and thus permit the heated air to pass from the interior ofthe drum and to circulate through within the interior of be noted that each rack comprises side bars arting from the spirit V carried- Within the casing.

17 connected by end bars 18. The ribs 19 have their ends formed upon or secured in any suitable manner tothe end/bars and these ribs 19 extend parallel to the side bars 17. By referring to Figs. 1 and 3 it Will'be noted that the ribs 19 are comparatively thin and project upwardly for a distance beyond the 17 and end bars 18 of their respective racks. These [racks are ofsuch shape as't'o' Conform to the shape of the casing 7 antl 'for' this reason may be positioned upon the cleats 12 Therefore, the heat which passes from the "heating druin will freely circulate through the racks, as Willbe hereinafter fully set'lortli;

The clips are similarly constructed and are" formed from single strips of ma terial comprising a substantially inverted U- sliaped body 20 wliiehha's its side" portions secured together, thus facilitating the grip oii'a rib 19. The lower portiohso'l the body 20 are curved outwardly'toio'rm retaining fingers 21 which are curved up-Wa'rtlly to eittend parallel to the body 20 and'Whi'ch have their upper ends sharpened as indicated at 22'. Thusit will be seenthattlieclips are substantially JV-shaped for facilitating the gripping or the-ribshnd' at thesame time allowing ears of corn tobe inserted or placed uponthe pointed ends' QQ-df the fingers 21'. Before a rackis placed within the casing, the clips'have ears of coi'n' place'dthe'reon as indicated in Fig. 3 andthen the'clips 'n'iay in tu'rn be plaeedu'pen thei'ibsoi the'ra'ek until the rack is filretl ,"tlieirtl'ie rack may beplac'ed Within the casingto' rest upon a pair of cleats 12 i In orderw reintorce the central ortions of the racks after commas been placed thereon and t'hey are-"carried Within the Gas ing,'the hangenbafs 23 may beempleyeu, as illustratedin*Fig. 1. The hahgerbars have hookedends 24 whlch may be inserted tlirou'gh suitable openings formed" in thefibs 19 of the racks and for thisreason the racks maybe hooked together for reinforcing the racks;

Under ordinary conditions'se'ed corn is selected and is hungvvithin' abuildi'ng where the sprouts are liltely'to freeze" antlthus'rui'n the corn for seed purposes.

However, With the present invention, the selected" ears of; corn are inserted upon the pointed ends' 22 of thefi'ngers 21 as hereinbefore specified, andas these c'lipsar'e filletl, they are in turn placed in gri pingrengag ifi'iit upon a rib, as; illustrated in, Figs. :1

and 3. After the ribs of a r a'ck haveteen filled, the rack may then be inserted in the casing to rest upon a plurality of thecleats; The hanger bars, 23 may then'bein'sei-t'ed through theracks to engage'thecentral ribs as shown in Fig. 1 for reinforcing th'e 'rac ks at their 'ceiitfttlPbitififis. At this fiiifie' the.

upper surfaceofthe side bars heating drum may be placed Within the easing on the lowest plate, as illustrated in i *1. ser ted Within the casing and then the doors 8 maybe closed. As the drum is heated, it is obvious the heated air Will pass-from the drum through the necks 16 whilethe'ilrtun willalso radiate*Qheat. This heat and heated air will pass around through the racks and owing to the s acingapartefithe ears ar ried within tlieeasi'ng and their; veitieat position, the 'heat yvill easily-circulate areund betvveen' theears of orn: 'Ihe' moisture-aria ing "from the corn Which isflry-ingas well as the-rising heat inaypass fhom thecasihg through the ventilator-"- 9. It isobvious as many ears of corn as desired may be plaeti Witl1i1rthe"ca'sing and due'to-the artificial. heat will be quickly dried and h" n inaybe removed and placed in a desired "receptacle without danger, of injury due to atinospheric conditions. I The foregoing description anti the draw-- ings have reference to what-may be considered the preferred, or 5 approved, of my== invention. It is tobe understood that I may make 11611 changes in ed-nst uetioii and arrangement and cembiiiatimdfflpartsfmateriztls, dimensions, steam; as may prove eixpetlient- 'anth f'all within the scope or the appended claims.
